Crude Oil Distillation Units (CDU's) for Sale

Used 65,000 - 170,000 BPD Atmospheric Crude Oil Distillation Unit (CDU) with Vacuum Distillation (VDU) built in 1976. This CDU & VDU is capable of 65,000 - 170,000 barrels per day. The unit preheats, de-salts, and separates crude oil into naphtha, No. 2 fuel oil, heavy atmospheric gas oil (HAGO), and atmospheric tower bottoms with the crude tower and preflash drum. The HAGO and No. 2 fuel oil are stripped of light hydrocarbons and dried respectively. Naphtha is further refined by the debutanizer tower, which separates the unstabilized straight run naphtha into a bottoms product of naphtha and an overhead stream of liquefied petroleum gas. The sour water stripper removes hydrogen sulphide, ammonia, and other impurities from sour water, then returns it to the desalter.

Used 25,000 BPD Crude Refining Unit (Topping Unit) built in 1940. The unit was designed to process two types of crude oil feed: light crude of 34° API and heavy crude of 20° API. The unit is designed to be able to reprocess 1,500 BPD of out-side off-spec naphtha in addition to and concurrent with the 25,000 BPD crude fractionation. Provisions are included to handle off-spec conditions either (1) for too high a vapor pressure or (2) with too high an end point. Alternate feed locations are to the Main Fractionator for conditions (1) or to the Naphtha Stabilizer for condition (2). Process Temperatures: Crude Charge 100 °F, Naphtha Product (max) 100 °F, Kerosene Product (max). 125 °F, Diesel Product (max) 150 °F, Atmos. Gas Oil (max) 175 °F, Residual Fuel Oil 200 - 300 °F. Column size basis 87% of flood (max). The Naphtha Stabilizer is designed to stabilize the light naphtha product (Pre-flash Tower Overhead) to 9# RVP (max). Design includes capability for re-running up to 1,500 BPD of off-spec.

Used 85,000 BPD Crude Oil Refining Unit (Atmospheric and Vacuum Distillation) built in 1975. This complete crude unit produces naphtha, distillate, asphalt and off gas.

Used 14,000 BPD Crude Oil Refining Unit / Topping Unit built in 1978. This complete crude unit produces Diesel, Naphtha, Kerosene, Butane Mix and Light Gasoline. This crude is heated through a series of two existing parallel sets of heat interchangers on the way to the existing Desalter. The heated crude then feeds the Preflash Column. The remaining bottoms and/or a parallel stream of heated Crude are fed forward to the fractionating column.

Used 117,000 BPD Crude Oil Distillation Unit CDU from within a refinery complex, built in 1966. This CDU crude oil refinery unit is capable of 117,000 barrels per day atmospheric and is currently used to produce fuel oil, ultra low sulfur diesel, heating oil, kerosene, naphtha and off gas.

Used 1,500 BPD Vapor Recovery & Hydrocarbon Liquids Distillation Unit built in 1998. The unit was originally designed to use lean oil absorption technology to collect hydrocarbon vapor/air mixture from marine docks, tank truck, railcar and storage tanks, and then to use distillation process to make gasoline, diesel and oil products. The unit includes three main process sections: (1) Vapor recovery (lean oil absorption), (2) Regeneration of absorbent fluid, (3) Distillation. The vapor recovery consists of the hydrocarbon vapor/air mixture entering the bottom of a packed column, counter-flowing upward, impinging on absorbent wetted packing. A chilled absorbent fluid enters the top of the tower and begins a downward flow wetting the packing. The air exits the column top stripped of the hydrocarbon vapors. The hydrocarbon vapor, captured by the absorbent fluid, exit the column bottom. If the feedstock is not vapor, the production skips the absorption and regeneration sections, and directly starts from the distillation. It is a good processing unit for condensate, light crude oil, waste oils.
